I found out all I had to do was go into my computer, under the hard drive, my user name and delete the .limewire folder. I restarted my computer and started limewire up with no prob. The first time I tried to start LW wo restart my computer but it did not work. I did not have to do anything else. I downloaded the gutnella.net file and put it on my desktop but never had to use it.
I have windows XP SP2 and many java updates.
Works for now.
